So apparently Rob wrote this song around the first Twilight movie shoot or shortly there after. The guy performing it, Lee MacDougall, is a friend of Lizzy's (Rob's sister). Listen to the lyrics and it's obvious who it's about. I would pay $bigbucks$ to hear Rob sing it!!!

"...She's got these big green eyes..."

"I'm falling in love for the last time... I'm falling in love with a girl that ain't mine..."

I got this info over on robsessed in the comments section of the pictures above. I don't know if it's true or not, but those lyrics are pretty compelling for me to believe it's true!
